Definitions

  • the present invention relates to a brake apparatus. More particularly, the present invention relates to a brake apparatus for a two-wheeled vehicle.
  • a two-wheeled vehicle is equipped with a brake system to slow or stop its moving by applying friction upon its wheels.
  • a rider uses both hands to press two brake levers, fixed on the handlebar, to control a front and rear brake of the two-wheeled vehicle.
  • it would be dangerous if the rider presses either one of the brake levers too hard to make the vehicle's wheel to be locked by the front or rear brake.

  • the braking system brakes the front wheel when the rear wheel braking device is in its braking position.
  • US 2009/0302565 discloses a brake system including a first brake to apply a first brake force on a first wheel of a vehicle and transfers the first brake force to physically actuate a second brake to brake a second wheel of the vehicle.
  • the present invention is directed towards a braking apparatus that includes two or more brake mechanisms that are actuated by one or more brake controls, such as hand brake levers or foot brake pedals.
  • a first brake actuator actuates one of the brakes.
  • the friction force of the brake against a rotating structure then actuates a second brake actuator coupled to the second brake so that both brakes are engaged to slow or stop the vehicle.
  • the first brake that is directly controlled by the brake lever can be any brake on a vehicle.
  • the following description is primarily directed towards a two wheeled bicycle in which the first brake is the rear brake and the second brake is the front brake.
  • this configuration is exemplary embodiments of the invention.
  • These same designs and operating principles can be applied to any multiple wheeled vehicle and the first brake can be any brake on the vehicle.
  • the scope of the application is intended to cover the inventive braking apparatus applied to all of these different vehicle configurations.

  • the present invention is directed towards a brake system 10 that can be used for bicycles and other vehicles supported by multiple wheels.
  • the inventive braking system 10 that can include two or more brake mechanisms 15, 19, 23, 27, 31 that are actuated by one or more brake controls 11, such as hand brake levers or foot brake pedals.
  • a first brake actuator 13 actuates the first brake 15.

  • the rear (first) brake may control multiple brake actuators 17, 25.
  • the brake controls 11 can actuate the first (rear) brake actuator 13 which is coupled to the first (rear) brake 15.
  • the braking friction of the first (rear) brake 15 actuates the second (front left) brake actuator 17 which is coupled to the second (front left) brake 19.

  • the braking friction of the third brake 27 can actuate the fifth brake actuator 29 coupled to a fifth brake 31.
  • This sequential brake actuator configuration can continue to three or more brakes.
  • the following description is primarily directed towards a two wheeled bicycle in which the first brake is the rear brake and the second brake is the front brake.
  • the first brake is the rear brake
  • the second brake is the front brake.
  • these same designs and operating principles can be applied to any multiple wheeled vehicle and the scope of the application is intended to cover the inventive braking system applied to all multiple wheeled vehicle configurations.
  • Normal bicycle brakes include two hand levers which are used to individually control a front brake and a rear brake.
  • a problem with existing brake systems is that the bicycle rider must be careful when applying the brakes because if the front brake is locked, the stopping force can flip the rider off of the bicycle.
  • There are several techniques for efficient braking on a two-brake bicycle The one most commonly taught is the 25-75 technique. This method entails supplying 75% of the stopping power to the front brake, and about 25% of the power to the rear. Since the bicycle's deceleration causes a transfer of weight to the front wheel, there is much more traction on the front wheel. However, excessive front braking force can cause skidding of the front tire which can cause the bike to flip forward over the front wheel and probably injury to the rider. Excessive rear braking force can cause skidding, but will not result in the bike flipping.
  • the present invention is directed towards a brake system and apparatus which allows the rider to quickly stop the bicycle or other vehicle very quickly, but prevents the front wheel from locking up or being slowed too quickly.
  • the brake system is also compatible with existing brake designs and can be produced in a very economical manner so that bicycle riders will not have to pay a significant amount of money for these very important safety features.
  • the inventive brake system can be retrofitted onto existing bicycle brakes and in other embodiments, the inventive brake system can be incorporated into the designs of the brakes.
  • the bicycle 100 has a frame 101 on which a front wheel 107 and a rear wheel 105 are rotatably mounted.
  • one or two brake levers 102 are fastened on a handlebar 103 and the lever(s) 102 are connected to a rear brake actuator 140 which is coupled to a rear brake 104.
  • a front brake actuator 150 is coupled between the front brake 106 and the rear brake 104.
  • the rear brake 104 can include one or two inventive brake pad assemblies.
  • the brake pad assembly In response to the direct contact between the brake pads with the rotating braking surface, inventive brake pad assembly actuates the front brake actuator 150 which causes the front brake 106 to be applied to the front wheel 107 or other front wheel braking surface.
  • the brake pad assembly is pulled away from the rear wheel 105 and the brake pad assembly releases the front brake actuator 150 which releases the front brake 106.
  • the weight of the rider can shift forward and the deceleration force applied by the front wheel 107 at the point of contact with the ground can cause the rear wheel 105 to be lifted from the ground.
  • This loss of surface contact will reduce or eliminate the rotational force applied by the ground to the rear wheel 105.
  • the actuation force applied to the front brake 106 is proportional to the rotational force of the rear wheel 105, the braking force applied to the front wheel 107 will also be reduced until the rear wheel 105 regains contact with the ground.
  • the contact will generate a rotational force to the rear wheel 105 and the inventive brake pad assembly will be actuated again and apply more force to the front brake 106.
  • the inventive braking system and brake pad assembly prevents the front wheel 106 from skidding which allows the rider to remain in control of the bicycle even if excessive braking forces are applied. Since the front brake 106 force is controlled to the rear wheel rotational force 105, a rider can increase the braking force by moving as much body weight over the rear wheel 105 as possible during braking. However, even if the rider shifts his or her weight forward while riding, hard braking will not cause the bicycle to stop in a manner that would flip the bicycle over the front wheel 107.
  • FIG. 3 illustrates a brake system according to one embodiment of this invention.
  • the brake system can include a brake lever(s) 202, a first brake actuator 203, a first brake which can be a rim brake 206a, a disk brake 206b or other type of brake, a second brake actuator 250 and a second brake which can be a rim brake 206a, a disc brake 206b or any other brake mechanism.
  • the brake lever 202 When the brake lever 202 is squeezed, it transfers a braking force to the first brake actuator 203 which applies the first brake 206a or 206b.
  • the friction force of the brake pad assembly in the first brake 206a, 206b transmits a braking force to the second brake actuator which actuate the second brake 208a or 208b.
  • FIG. 4 illustrates a brake system according to another embodiment of this invention.
  • the brake system may include two brake levers 302a, 302b, a first brake actuator 309, a first brake 304, a second brake actuator 350 and a second brake 306.
  • two brake levers 302a, 302b are used to actuate the first brake 304.
  • the first brake actuator 309 can be a cable that can be split into a first brake cable 309a and a second brake cable 309b. This configuration divides the first brake actuation force between the first brake cable 309a and the second brake cable 309b which are respectively pulled by a first brake lever 302a and a second brake lever 302b.
  • a rider may use both hands to apply brake forces on the two brake levers 302a, 302b to actuate the rear brake 304.
  • the operator can still use either one of the two brake levers 302a, 302b alone and individually to actuate the first brake 304.
  • the first brake is actuated, the movement of one or more of the brake pads in the inventive brake pad assembly will actuate the second brake actuator 350 which transfers a brake force to the second brake 306.

  • two brake levers 302a and 302c can be coupled to a first brake actuator that includes a brake cable 309 and a brake cable housing 310 that surrounds a portion of the brake cable 309.

  • the brake pad assembly 403 can also include a layer of lubricious material 412 such as Nylatron, Teflon, graphite or other low coefficient of friction and high compression strength materials. Alternatively, the brake assembly 403 components can be made of these low friction materials.
  • the orientation of the slider assembly 403, brake pad 402 and guide 407 on the bicycle can depend upon the position of the brake 401 on the wheel. If the brake 401 is located on the upper half of the rim 411, the described and illustrated positions are correct.

  • the brake cable 122 tension force can be proportional to the friction force of the brake pad 402 against the moving rim 411. A higher braking force applied to the first brake will result in a higher braking force applied to the second brake through the brake cable 122. However, if the rim 411 loses traction with the road, the rim 411 may stop rotating and the friction force that creates the force that pulls on the brake cable 122 and the brake force applied to the second brake are reduced until the rim 411 regains traction and begins to rotate again.

This movement causes the brake cable housing 128 to be compressed. Although the guide 406 and brake cable 128 may not move, the movement of the brake cable housing 128 results in tension in the brake cable 122 which actuates the second brake.
